To Vent Open

Opening the sunroof glass, to the vent position, can be done when it is between fully closed and partially vent. Pull down on the front of the switch. This will apply the sunroof switch low reference circuit to the sunroof switch open vent signal circuit. Holding the sunroof switch in the vent position will cause the sunroof switch open vent signal circuit (12 V reference) input to be pulled to 0 V. The constant low input to the sunroof control module indicates an open vent request. Once the open vent request has been initiated, the sunroof control module will drive the motor in the closed direction (to vent position) until the sunroof motion is terminated by either:

• Motor stall is sensed because the sunroof has reached its limit of travel.
• Releasing of the sunroof switch.
